Solar Panel Cost in VIC (2026)
GradeSExcellentModel VIC solar ROI with local electricity rates, STC rebates, and installer cost benchmarks.
Last updated: 2026-06-25 · Source label: AEMO electricity data, Australian installed-cost benchmarks, BOM/PVGIS solar assumptions, Clean Energy Regulator STC policy context
Victoria has the most generous state-level solar support in the country through the Solar Homes program, which offers eligible households a rebate of up to A$1,400 plus an interest-free loan of up to A$8,800 — on top of the national STC discount of ~A$2,700. That stacking matters because Melbourne's solar resource is more modest at 4.0 peak sun hours per day, the lowest of the mainland capitals, and installed costs sit around A$1.05/W (about A$6,930 for a 6.6 kW system). Grid electricity averages 25c/kWh, while the minimum feed-in tariff set by the Essential Services Commission is just 3.9c/kWh, with retailers typically paying 5-12c/kWh. With lower sun and lower export values, self-consumption is the priority, and the Solar Homes rebate is what pulls payback down to a typical 5-6 years. Eligibility is income- and property-value tested, so confirm current Solar Victoria criteria before counting on the rebate.
